IT sirafijgg ANDREW-W. STEIGER, OF BRIDGEPOR-T,

TYPEWRI'IER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YQRK TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, Annnnw W. S'rnmnn, citizen of the United States, and resident of Bridgeport,- in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type- W'riting lilac-l'iines, of which the following is a specification.-

My invention relates to typewriting inachines and more particularly tothe ribbon vibrating mechanism of visible typewriters.

My invention has for its principal object to provide improved means for controlling the height to which a ribbon vibrator is thrown at each key stroke in order to vary the widthwise part of the ribbon that is I' have provided mechanism including a hand-operated device by which the yibrator can bQ CZLHSQd to bring either one of a plurality of stripes of theribbon to the printing point, and also'an automatically operated device for causing the height to which the vibrator is thrown to be varied progressively in order to nsenp the entire wid.h ofa ribbon. Both of these devices are present in the machine and can be used alternatively, the latter one when a smgle'color ribbon 1s used, and the former when a ribbon is used having stripes of different sorts of ink, such for example, as

black ink and red ink.

I attain the above and other ends by novel and improved devlces. These devices are employed in a machine in which the platen shifts, and they operate in either position of said platen.

My invention consists in the features of construction and combinations and arrangements of parts hereinafter set-forth and particularly pointed out in the claims.

In the; acco1npanying drawings, Figure 1 is a. front to rear vertical section of so much of a typewriting machine as is Inecessary to illustrate the application of .my invention thereto, and having my invention embodied therein. Fig. 2 is'a somewhatsimilar View but on a larger scale, with parts omitted and parts brokenaway, and illustrating the inecha nsin employed with a one color ribhon with the tntomatic cross feed in operation and with said cross feed in the position it occupies when ready for printing from the upper part of the ribbon. Fig. 8 is a' View similar to i'i'n: lower part ofFig. 2 but showmg the automatic cross feed in position for Specification of Letters Patent. Application filed Jannary 28, 1910. Serial No. 540,542.

Fig. 5'is a view similar to 2 but illustrating some parts not shown in said Fig. 52, and showing a two-color rib- I bon with the mechanism set to print frontthe upper stripe of said ribbon, and witlrthe parts in normal positions. Fig. (5 is a view, showing the same setting as shown in'F 5,- hut showing the parts in operated positions; Figs. 7 and S are similar views but with thejO A parts'set to print from the lower part of theribbon, the mechanism being in n0r1'na-l'posi tion in Fig. 7, andin operated position 'in" Fiji. 8. In Figs. 5, 6, T'and S some/of the-i devices have oecn omitted in order 1norefl5 clearly to illustrate the principle" of themechanism. 'Fig. 9 is a,fragmentary"front'- view of the-meclmnism shown in the'preced ing figures, with parts omit-teda'nd parts broken away. Fig. 10 is a horizontalsee tional view through the devices which sup? port. the vibrator operating lever.

My invention is applicable or ada-ptableifl generally to visible typewriters'bn't it isiherei shown applied to a Remington machine." v The main frame of this'machin'ecompr a' base 1 corner posts 2 and a top plate which supports stationary rails 4 on 'wl runs a carriage truck 5. A platen '6: a mounted in a platen frame 7 which isy u' ported on said truck by means of linhsS that said platen frame can be shifted up down, for upper and lower case 'printnr" Said platen frame. comprises across bar 1 on which journaled a roller 11 tl1at ri(le ona shiftrail 12. ySaidzrail-is supported by posts lti'which are carried-by a transverse bar 14 which in turn is supported by "rods 15 eajcl'i, at itslower end'nivoted at 16"to shift key lever 17, which at its forward-end shiftkeys at each side of theme-chine; an

- mounted in the base 1. The platennormally stands in its lower position, shown in Fig. 1, but itcan be shifted upward by depressing either of the keys 18. j The rail 12, cross bar 14 and posts 13 and 15 constitute a shifting frame for controlling the shift of the platen.

The printing keys 21 are carried on key levers 22 which are connected bylinks 23 with sub-levers 24,- which in turn are con-v nected by links 25 with front-strike type bars 26, said type bars being mounted on a stationary segment 27 by means of hangers 28. A universal bar 30 is hung by rods 31 to arms 32 projecting rearward from a transverse rock shaft 33, which is pivoted at its ends in the base of the machine. Near. its middle this rock shaft 33 has projecting therefrom anarm 34 which is connected by a link35 with the escapement mechanism of the machine.

The carriage feed mechanism includes a spring drum 36 which is connected'with the carriage by means of a. stra 37. spring drum drives a beveled gear 38 that meshes with another bevel gear on a transverse drivin shaft 40 which in turn carries at each of its ends a beveledpinion that the Vibrator in place and leave it frec to "across to the guide and spool at the other side of the machine. The driving shaft 40 'is arranged to be shifted lengthwise to gear it to one or the other of the spools in a manner well known in the art.

The vibrator and its associated parts can be best understood from Figs. 5 and 9. A

bracket 47 is secured by screws 48 to a fixed }part of the machine, the type bar segment 27 eing used to support said bracket in the present instance. to a point in front of the platen and a little below thewriting line and terminates in a printing point indicator or pointer 50. The

-' vibrator consists of a plate of sheet metal -hav 1ng at its upper end two-arms with a space between them for the type to strike through, and each of said arms is formed I with a. slot 51 through whichlho ribbon is threaded. The vibrator lies just back of the bracket 47 which constitutes a guide for said .'vibrator. To this end two cars 52am .bent oil fromjthe ri 'ht and lei t hand edges of the vibrator and are bent around the edges of the guide or bracket 47 so as to hold move up and down. 'lhe'lo'x-ver end of the vibrator is. secured by rivets 55 to a. bar or stern 54 which at its lower end has a headed pin-55 projecting therefrom into a slot 56 in This This bracketextends up of this arm 34 on the lever the arm 34 is made with an upward angle as shown and at said angle a lever 77 is i 121:.

the forward end of one arm of a bell crank 57 which constitutes the operating lever for the vibrator. The lever 57 is pivoted at 58 in a bracket 60 which is secured by screws 61 to the shift rail 12 and the cross bar 14 of the platen shifting frame so that said pivot 58 moves up and down with the laten when the latter is shifted. The brac ret 60 consists of a. piece of sheet metal, T-shaped at its upper end as shown in Fig. 9, and hav ing a slot 62 through which .the lever 57 plays. The bracket 60 has two cars 63 bent back from its edges and the pivot 58 passesthrough said ears as shown in Fig. 10. Twowashers G4, 65 surround the screw 58 and one of said washers is shouldered as shown to-providea bearing for the lever 57, the two washers together constituting a guide to prevent wabbling of the lever. v

The depending arm of the lever 57 has pivoted thereto at (36 a rearwardly extending link 67 which at 68 is pivoted to the up wardly extendingarm of a lever 70 of the first order. Said lever 70 is mounted in a slot in'the rear end of a bracket 71 which is secured by screws 72 to the rear face of the type bar segment 27, the lever 70 being pivoted on a pin 73, The lower arm of the lever 70 is formed with a stop lug 74 which normally contacts with .the' underside of the bracket 71 to limit the motion of the lever in one direction and the motion of said lever in the other direction is limited by an adj usting screw or stop 75 which is threaded withstanding the fact that the ribbon vi 'bratoi moves up and down with the platen.

The lever 70 is operated by the arm 34 t-hat'projccts from the rock shaft 33 and the variations in the throw of the vibrator are brought about by changin the operation 70.. To thisend mounted on said arm 34 by means-of a pivot screw 78. The pivotscrriw 78'is made with a, shoulder as- -i ndicat cd by dotted lines in Figrfl andthe left-hand end of said screw has a nut 80 threaded thereon t hold the screw in place. A washer 81 holds the lever 77 a short distance to the right of the ell-c1134.

The upper armof the lever 77 has a I'adltll slot 82 therein which embraces a headed pin projectingi'rom the lower arm of the lever 70. In order to provide for an adj ust- 1 lever there mounted on the screw a washer :86 and a nut 87. By loosenin said nut the.

'screw can. be moved lengthwise ot the slot -84; and it can be secured rigidly 1n ad usted position by tightening the nut. The lower arm ofthe lever 77 is otf-set. to we the front, of the machine as shown and has a longitudi- -nal slot'SS formed therein, this slot not e.

tending radially of the lever. 4

A link orcontroller 90 is pivoted to one side of the arm" 34: on apivotscrew .91 and :the forit ard end of this link has a shouldered rivet '92, (Fig. 11) that is adapted to play in the slot 88in the lever 77. The relation of the several parts is such that it the link 90 be turned about its pivot to move the pInlJZ along the slot 88 this will result in turning the lever 77 about its pivot 78 and thus changing the relation of said lever 7 7 to the rock shaft 3?) and to the universal bar. lint when said link is held in any one position and the pin 92 retained in any one position in the slot 88, then the lever 77 is rigid on the 211-11134 and becon'les in ett'ect merely a part or extension of saidarm. Considering the rocksl'iatt 3?) and its arms :32 and 3st, 77, as a lever, the ell'eet of adjustingjthe link 90, is

. to change the angular relation of the arms of said lever..

The rivet 92 has a'screw 93 and another screw 9t co-axial therewith, and the connections of these screws will he explained presently. Whenthe parts are in the positions shown in. l igj. 7 it will he noted that the stop hip; Tatis in contact with the bracket 71 wliichlilnits the "urnval'd motion of the universal bar. It now a key be depressed the parts will 'l'l'lOVU to tlie positions shown in Fig. 8 and the lever will make its full extent of motion and be arrested bythe stop screw 75. If ,the controlling link be moved down to-the' position shown in Fig. 5,

thellever 77 will l'lQ JOflltttl about its pivot Fig. 5, ,this position being iin'licated.

TSfthH lower end of said lever moving toward the rear of the machine. This tends to. move the upper end of the lever toward the front of the machine but, as the stop lug T4; is resting against the bracket 7]., the up- "per end of the lever 77'cannot move toward the front. The arm fi l: is therefore moved slightly toward the rcar,",droppi11g the uni .versal bar down to the position shownin by The pos tion broken lines at 30 in .Fig.

30 of the universal bar is anintermediate position between t he position shown in' full lines 1n F1 T and the de )resscd ')()f ltl01'i shown in l ra. S.

' intermedjiate that shown in Fig. 7 and that shown in Fig. 5. i

The hand operated THQZII'ISfOl" shifting the link 90, comprises a handle 95 formed on the forward end of a lever arm 96, the rear end of which is pivoted on the cross rod 2tl, thc

handle 95 standing beside one of the corner posts 2 and in or convenient to the keyboard. of the n'iachilne. connected by a yoke'bar 97, (Fig. 9) with a rearwardlydirected lever arm 98 which is pivoted on the rod 20 approximately in front of the arm 34. At its rear end the arm 98 has a link 100 pivoted thereto at. lOl,

and the pivot screw 94 above referred to passes through the upper end of said link. In Figs. the position of thelink r00 is indicated by broken lines and it will be seenthat if the machine contained only the hand control and not the automatic control the pivot screw 94 might be tl'n'caded directly into the pin or rivet 92. In the construction actually shown thescrew 9-1;

indirectly connected with the pin 92 andthe action is the same as if it were directly connected to said pin. It will be seen that when the handle 95 is in the position shown in Fig. 1 the links 100 and 90 will occupy The lever arm no is .lt will be seenthat the downward adjustment of the link 90 drops the positions shown in F 5 and ti and the machine will be set to print'trom the upper stripe of the ribbon; and that. if the said handle 95 be depressed the links 100 and 90 will be moved up to thepositions shown in Figs. 7 and S and the machine will be set to print from. the lower stripe of the ribbon. The forward end of the lever 96 passes through a guide slot in a bracket- 102 which is secured to one of the corner posts 2 of the slot has an oft-set forming a shoulder 10% (Fig. 9) so that when the handle 95 is depressed it can he PIISlltIld llillt to the left and the arm 96 be etulght under said shoulder and held in depresseduposition. The parts are turned to the position shown in Fig. 1 by means of a COllOtlSpl'll'lg 105 which is connected at one end to the yoke-bar 97' llO machine by means oiscrews 103. Said guide arm 34 is here shown as built upby inserting a sheet metal arm into a lug projecting from the shaft 33 and securing said sheet metal arm in place by'rivets107. It may also be remarked that when the parts arein the positions shown in Figs. 7 and 8, the link 100 is not co-axial with the shaft 33 so that when said shaft is rocked by the depression of the universal bar to the position shownin Fig. 8 the pin 92 is caused by the link 100 to slide a short distance in the slot 88. This slightly modifies the action but the parts are so adjusted as to give the right extent of throw to the vibrator. hen the parts are in the position shown'in Fig. the pin 92, the shaft 33 and the pivot 101 are more nearly in a straight line so that when the universal bar is depressed to the position shown in Fig. 6 the pin 92 stands nearly stationary in the slot 88. I r The automatic shift of the link 90 is effected fromthe ribbon drive shaft 40 by means of an eccentric 108. having a hub 110 which is secured to said shaft by a set screw 111. Said eccentric has a strap 112 from which two pins 113 project into the branches 114 of a bifurcated link or connecting rod 115, the lower end of which is connected with devices whereby the connecting rod 115 and the link 100 can be caused alternatively to control the link 90. These devices can be best understood by reference to Figs. 2, 5, 11 and 12. A link 116 is formed with a long slot 117 and the forward'end of said link is bent back forming an car 118, and the rear end of said link is similarly bent forward forming an ear or branch'1'20. The pivot screw 94 at the upper end of the link 100, is threaded into thecar 118 and the lower end of the connecting rod 115 is pivoted to the car 120 by means of a pivot screw 121. on its right-hand end with a reduced part that passes through the slot 117 and the screw'93 is threaded into the end of said pin 92. A washer 122 lies between the head of said screw 93 and t-helink 11 6. The conthe link 100 an 'the'handle 95.

struction is such that the link 116 can be slid along the pin 92 and when said link is in its rear-most position shown in Fig. 5 the screw- 94 is substantially co-axial with the screw 93 andthe pin 92 so that said pin 92 and the link 90 are lacel under the control of parts are in this position the up anddown motion of the connecting rod due to the rotation of the eccentric 108 merely rocks the link 116 about/the pin 92 as a center without affecting said pin so that said connectihgrod 115 has no effect on the link 90.

l/Vhen the link 116 is shifted to its exl rmnc forward position shown for example in Fig. 2, the screw 121 is substantially co-axial with the pin 92 andthe screw 94 stands out The rivet 'or pin 92*is formed When the in front of said pin as shown in Fig. 2. in

this position of the parts the rotation of the eccentric 108 moves the pin 92 and link 90 slowly back and forth between the positions shown respectively in igs. 2 and 3 and in the first of which the parts are'set to cause the ribbon to print from the upper part thereof and in the other of which the print will be from the lower part of the ribbon. In intermediate positions of the eccentric the print will be from the intermediate parts of the ribbon. As the shaft 40 turns, the

parts are slowly moved from one of these positions to the othenand, as the ribbon is being fed longitudinally at'the time, the

printing will take place along a sinuous line on the surface of the ribbon and the entire width of the ribbon will be utilized. When the connecting rod 115 is thus in operation on the ribbon mechanism itis immaterial in which position the handle stands as an up and down motion of the link w'l merely swing the link 116' about the pin 92' a center without affecting said'pin. In order to retain the link 116 in either of its two positions I have inoun'ted thereona latch 123, said latch being pivoted to the linkat 124 and the free end of the latchbeing bent unde'rthe link at 125. The latch 123 is formed at its ends with shoulders 126 and. 127 which, when the latch is inits opv crative position shown in full lines in Fi 12, closes the middle part of the slot 11 and confines the pin 92 to one end of said slot. The latch is made of thin metal and slightly,bent inward toward the link 116 so that when it is up in operative osition it is retained in such position by. iction, but

the latch can be pulled down to the position shown in broken lines in Fig. 12in order to shift the link 116.

confusion in the showing.

If the automatic crosswise feed is not wanted in the machine the link-116 and the eccentric 108 and connected parts can be L omitted and the link 100 connected directly This link. 116 is i .omitted from Figs, 5-8 in order to, avoid and the lower end of the be connected (11? Versiug the directionof ribbon feed and of course the eccentric 10S is'carriedwith it;

This motion is slight, however, in co1nparison with the'length of the rod '115, and does.

not harm.

' The cscapcmcnt comprises feed dogs 130 which cooperate with an escapement wheel 131 which is connected with the carriage by means of a rack 132' and pinion 133. The dogs 130 are mounted on a dog rocker 134 having a horizontal arm to which the link can be brought under the control of either of lS CtIuDI'lQCiGCl.
